UNITED 'STATES' ATENT orncs FRANK G. IBBOTZ, OF KOHLEB, WISCONSIN,ASSIGNOB TO KOHLER GOIPANY, OI KOELEB, WISCONSIN, A CORPORATION OFWISCONSIN START AND STOP SWITCH FOR COMBINATION DISHWASHER AND SINKApplication filed July 6, 1928. Serial No. 120,787.

This invention has for its object to provide. a start and stop switchfor combination dishwashers and sinks so constructed and arranged as toconstitute a safety feature preventing the starting of the motor whenthe cover is open and inaccessible to small children.

Such dishwashers provided as usual with controlling switches installedunder the m apron or in the wall are apt to have the motor started whilethe cover is open with a consequent splashing of water in all directionsand, being accessible to children, they are apt to be injured if, intheir inquisitiveness, they start the motor and cause the machine to beoperated. This invention has for its object to avoid the possibility ofsuch mistakes and such danger.

With -the above and other objects in view the invention consists in thestart and stop switch for combination dishwashers and sinks as hereinclaimed and all equivalents.

Referring to the accompanying drawing the figure represents a verticalsectional view of a combination dishwasher and sink having amotor-control switch constructed inaccordance with this invention.

Inthis drawing, indicates the dishwasher receptacle of a combinationdishe in present use, the motor 11 thereof positioned at the bottom anddriving rotating dishwashing mechanism 12 indicated in dotted lines. Acover 13 with flexible sealin lip is hinged at 14 to the back panel 15 othe porcelain enameled combination fixture and is adapted to make atight fitting closure with the rim surrounding the receptacle 10 toconfine the water thereto. The cover 13, when open, swings back towardthe back panel 15, as shown by dotted lines, and mounted on the backpanel 15 in position to be engaged by the coverwhen open is a bumper 16of rubber or other cushioning material, which constitutes the handle ofa switch 17 for controlling themotor. The switch handle is thus locatedwhere it will be inaccessible when the cover is open, making itimpossible for themotor to be started at such times to splash the waterover the room and insuring the closing of the cover before the motor isstarted.-

A tubular sheet metal conduit 18 extends from the switch 17 to a pointbelow the back panel 15 and forms a housing to rotect a cable 19 passingtherethrough rom the switch 17 to the motor 11, there being anothercable 20 extending from the motor to an attachment plug 21 removablyfitting in a service outlet 22 in the wall of the room.

The switch handle 16 does not operate the switch when pressedlongitudinally as by the pressure of the open cover, but it ispreferably of that type which may" be swung in any direction to operatethe switch, first to close the switch and then to open it. Theconstruction of such switch is not shown as it forms no part of thepresent invention and is in common use. As the cover is usually ofglass, the switch handle is preferably provided with a rubber tip orcovering.

The switch is thus incorporated in the fixture itself and the handle isconvenient for operation without being accessible to small children.

As the present invention in commercial practice is embodied inclotheswashers as well as dishwashers and in individual units as well ascombinations with sinks, the term dishwashers and the like as hereinused is intended to include all such devices and devices of likecharacter.

What I claim as new and desire to secure by Letters Patent is:

1. In a dishwasher or the like, a receptacle, a motor-driven mechanismtherein, a hinged cover for the receptacle, a bumper against which thecover swings when opened, and a switch for the motor operated by saidbumper as a handle.

2. In a combination dishwasher and sink having a back panel, adishwasher recep tacle, motor-driven dishwashing mechanism therein, acover for the receptacle hinged to the back panel, a cushioning bumperon the back panel against which the cover swings when open, and a switchfor the motor. behind the back panel, said bumper constituting thehandle for said switch.

3. In a combination dishwasher and sink of porcelain enameled warehaving a back panel, a dishwashing receptacle, motordriven mechanismtherein, a cover for the receptacle hinged to the back panel, aresilient bumper on the back panel engaged by the cover in its openposition, a switch for the motor on the back of the back panel saidpumper constituting the handle said switch, a sheet metal conduitextending from said switch to beneath the back panel, a cable extendingthrough the conduit from said switch to the motor, a cable connectedwith said motor, and an attachment plug thereon.

4. A stationary plumbing fixture of porcelain enameled ware comprising areceptacle having a back panel rising above it and adapted to fitagainst the Wall of the 5 room,- a motor-driven water agitatingmechanism within the receptacle, a hinged cover for the receptacleadapted to be opened to a position close to the back panel, and a switchfor controlling the motor mounted on the back panel in position to berendered inaccessible by the open cover whereby it cannot be operated tostart the motor while the cover is open.

In testimony whereof I aflix my signature.

FRANK G. BROTZ.
